As long as the radius of the curve is not larger than the thickness of the mdf you should be fine.

Those look like 1/2" round-offs so you should have no issues: none of the "joint" will be changed.

I just did that and I really can't tell you how beautifully MDF routes. I couldn't believe that cutting the full 1/2" round-off would be effortless and only take one pass.

You will test the depth setting on scrap until you see it's "really" round. To do that, you start setting the "tiny" point on the outside of the bit so it's just a little above <too deep> above the "table" of the router. When you make a test cut, it will have a little "shelf" on the side of the cut that points up through the router.

The quickest way to get an excellent depth setting is to use a small (6") ruler. Set your test depth and then drag the ruler across the bottom of the router from the outside to the center and see if it "hitches" on the outside of the router bit. I look at this with a lighted magnifier and you really can see how far up/down you need to change the depth.

How else would you do this?

This is how I round the front panel. You can do the same thing with the top and bottom of the box. The router bit to use is Round Over Edge Forming Bit.
